Most of the women will be clean within 1 month after the birth of the baby. If the milk is still not clean for 60 days, it is considered that the uterus is not recovering well, and it is necessary to see if there is residue in the uterine cavity. If the uterus is not recovering, you can take medicines to promote the recovery of the uterus, such as motherwort granules, new biochemical granules, etc. You can also use uterine contraction to promote the contraction of the uterus. If there are residues in the uterine cavity that lead to unclean discharge, you should also use the above mentioned medications to promote the recovery of the uterus after the operation. Also, due to the prolonged bleeding, antibiotics are needed to prevent infection that may lead to inflammation of the reproductive system.
